What is Native Machine Code?
Native Machine Code is the binary (0s and 1s) language that a computer’s CPU (processor) can directly understand and execute. It is the lowest level of code, making it the fastest and most efficient way to run a program.
How is Native Machine Code Created?
1️⃣ Write Code→Developers write code in high-level languages (C, C++, Java, etc.).
2️⃣ Compile → A compiler (e.g., GCC, Clang, JIT) converts the code into machine code.
3️⃣ Execute →The CPU executes the machine code directly.
Why is Native Machine Code Important?
✔ Super Fast – No extra processing like in interpreted languages.
✔ Efficient – Uses system resources optimally.
✔ Direct CPU Execution – No need for translation at runtime.
Examples of Native Code Execution
✅ C and C++ Programs – Directly compiled into machine code.
✅ Assembly Language (ASM) – Almost 1:1 with machine code.
✅ Android NDK Apps – Written in C/C++ for better performance.
Native vs. Non-Native Code
| Feature | Native Machine Code | Non-Native Code |
|---|---|---|
| Execution Speed | Very fast | Slower |
| Translation | No extra translation needed | Needs an interpreter (e.g., Python) |
| Dependency | Runs directly on CPU | Requires runtime environment (JVM, .NET) |
Summary
Native Machine Code is the fastest way a CPU can execute instructions.
It is generated from compiled languages like C, C++, Rust.
Used in high-performance applications, including games, operating systems, and embedded systems.
Native Machine Code in Flutter
In Flutter, apps are written in Dart, but they do not run as Dart code on the device. Instead, Flutter compiles Dart code into native machine code, making Flutter apps fast and efficient.
How Flutter Converts Dart Code to Native Machine Code
1️⃣ Write Flutter Code → Developers write code in Dart.
2️⃣ AOT (Ahead-of-Time) Compilation → Flutter compiles Dart into native machine code for Android and iOS.
3️⃣ Runs Natively → The compiled code runs directly on the device's CPU & GPU without needing a separate runtime.
Native Code Compilation Process in Flutter
| Platform | Compilation Process |
|---|---|
| Android | Dart → Native ARM Machine Code (via LLVM) |
| iOS | Dart → Native ARM Machine Code (via LLVM) |
Why is Native Machine Code Important in Flutter?
✅ Faster Execution – Flutter apps run at native speed.
✅ No Performance Overhead – No need for a JavaScript bridge.
✅ Access to Native Features – Directly calls platform-specific APIs.
Summary
Flutter apps compile to native machine code for both Android (ARM, x86) and iOS (ARM64).
Uses AOT (Ahead-of-Time) compilation for better performance.
🔹 ]]No JavaScript bridge, so apps run faster and smoother.
